Science at key stage 3 (Year 9)

Unit 9H: Using chemistry

Prior learning

It is helpful if pupils:

have carried out a test for carbon dioxide
know that burning involves a reaction with oxygen in which oxides are formed
know that new materials are formed when chemical reactions occur and can identify evidence of these
have used symbols and formulae and word and/or symbol equations
recognise an order of reactivity of metals
